A vast array of broadcasting protocols has been developed to alleviate the Broadcast Storm Problem for single-radio single-channel and single-rate wireless networks. The emergence of Multi-radio Multi-channel and Multi-rate Mesh (M4) networks, however, brings a lot of new challenges, such as channel assignment, adjacent-channel interference, and network capacity. This project focuses on the design, analysis, and implementation of distributed broadcasting protocols for M4 networks. Challenges such as channel assessment and assignment, interference-aware metric design, transmission rate control, broadcasting tree construction, etc., are to be considered. In-depth theoretical analysis, simulations, and real-world network experiments are also conducted to evaluate the broadcasting protocols. This project also explores several educational innovations. These include the development of a novel three-layer teaching structure, efficient pedagogical approaches, and effective means of incorporating research into learning and education. As one important component of this project, outreach activities are developed for underrepresented minorities from local high schools with the aim of improving their academic performance. This research advances knowledge and understanding in the areas of wireless mesh networks, network optimization, and information dissemination. The problems studied are pragmatically and intellectually important and their solutions are critical to several areas such as the modeling of wireless communication links, networking traffic theory, and network performance analysis. The techniques developed in this project will benefit a broad spectrum of applications, including homeland security and military network deployment. Research results will be disseminated through a number of channels including international conferences, academic journals, seminars, workshops, and websites.

已经开发了大量的广播协议，以减轻单拉迪奥单渠道和单位无线网络的广播风暴问题。但是，多拉迪奥多频道和多速率网络（M4）网络的出现带来了许多新的挑战，例如渠道分配，相邻通道干扰和网络容量。该项目着重于M4网络的分布式广播协议的设计，分析和实施。应考虑挑战，例如渠道评估和分配，干扰意识的度量设计，传输速率控制，广播树的建设等。还进行了深入的理论分析，模拟和现实网络实验以评估广播协议。该项目还探讨了几项教育创新。其中包括开发新型的三层教学结构，有效的教学方法以及将研究纳入学习和教育的有效手段。作为该项目的一个重要组成部分，外展活动是针对当地高中代表性不足的少数群体开发的，目的是改善其学习成绩。这项研究在无线网络网络，网络优化和信息传播领域的知识和理解中提高了知识和理解。所研究的问题在务实和智力上很重要，它们的解决方案对于多个领域（例如无线通信链接，网络流量理论和网络绩效分析）至关重要。该项目中开发的技术将使包括国土安全和军事网络部署在内的广泛应用程序受益。研究结果将通过许多渠道传播，包括国际会议，学术期刊，研讨会，研讨会和网站。
